What was discovered
Physician Poiseuille experimentally determined in Paris how the pressure drop of a Newtonian fluid in laminar flow through a cylindrical tube depends on viscosity, flow rate, tube length and radius. Hagen published an equivalent result in Berlin in 1839.
George Stokes provided in 1845 the full theoretical justification of the law Poiseuille had obtained empirically.
